SINK-PIPE CAP.

$PEC IPICATION forming part of Letters Patent No. 302,269, dated July22, 1884.

Application filed December 13, 1883.

To all whom it may concern/r Be it known that I, CORNELIUS J. LYoNs, acitizen of the United States, residing in the city and county ofHartford, in the State of Connecticut, have invented certain new anduseful Improvements in Sink-Pipe Caps, of

p adapted to be placed directly over the mouth of the sink-pipe, andprovided with a nozzle for the regular discharge of such disinfectantinto the mouth of such pipe, a removable standard for the support ofsuch vessel while the sink is in use, a clamp for holding said vessel inplace, and a rubber ring upon which 'said vessel may rest.

In the accompanying drawings, in which like letters denote the sameparts throughout the several views, Figure 1 is a side view of myinvention and of a sink pipe and bowl, to-

gether with a portion of a sink and its support in longitudinal section,and Fig. 2 is a crosssectional view of my invention on the line a binFig. 1, as hereinafter more particularly explained.

' c is a dish, of brass or other metal not readily oxidable, is ofgeneral hemispherical form externally at the top and sides thereof, andis flat on the bottom, except at the middle part thereof, where thelatter rises re-entrant, like an inverted funnel, to near the top of thedish internally. This dish may be formed of a single plate of metal,- (2c f g; or the funnel g, with its flaring edges f, may be formedseparately from the hollow hemisphere d c, and the two parts cl 6 and f9 may be united by rolled joint, screw-joint, or in any other convenientmanner to make a perfect joint.v A spun joint is preferable. At the topand middle of the dish 0 the latter is provided externally with a fin-(No model.)

ger-piece, h, and the latter contains a center hole or screw-center, 75,to receive the setscrew j hereinafter mentioned.

At any convenient place in the upper part of (I e is an aperture ofconvenient size for the introduction of liquid disinfectants, ashereinafter explained, which is provided with the nozzle is andscrew-stop Z.

At any convenient place at the bottom of the dish 0 is a hole throughthe re-entrant plate 9, of convenient size for the discharge of thecontents of such dish, as hereinafter explained, which hole is providedwith a discharging-pipe and nozzle, m. The latter has a stop-cock, n,with finger-piece for regulating the flow, and terminates at the middleand bottom of the dish 0 within the re-entrant funnel g g. A side viewof m and it appears in Fig. 2. The plate f f is armed or covered 011 theouter part of its lower and fiat side with a ring or flat strip ofindia-rubber, 0, which is permanently affixed thereto. This annularstrip of rubber is of proper size to fit exactly within the flange p ofthe standard g, hereinafter to be mentioned. The standard q consists ofa flat ring of metal, which is flanged short distance from each other inorder that sink-water may pass freely between them when this instrumentis in operation, and yet are placed so near to each other as to preventlarge objects from passing between them. The removable standard (1 isshown in Fig. 2 separate from the disk 0 in the same figure. Thisstandard should be of such size as to extend over the extreme outeredges of the mouth of the sink-pipe to which the same is to be applied.The set-screwj works in any proper support attached to the frame orwood-work of the sink, and is adapted to enter the center hole, z, inthe finger-piece h.

Such being the construction of my improved sink-cap, the mode of itsoperation is as follows: Through the nozzle is the dish 0 is filled tothe top of the funnel g g with sulphate of LII iron, carbolic acid, orsuch other liquid disinfectant as may be .desirable. The stopscrewl isturned into 76, whereby the latter is closed. The stop-cock a is thenopened enough to allow the liquid to run or drop from m with the desiredrate or frequency of discharge. The dish is then placed upon itsstandard 1, with the rubber 0 and at least a part of the plate f withinthe flange p. The standard q is then put in position so that the teethare upon the upper surface of the bottom of the sink around the mouth ofthe sink-pipe, and the nozzle m, finger-piece i, and set-screw aredirectly over the middle of the mouth of such pipe. The set-screw j isthen turned down until the whole instrument is firmly clamped togetherand held in position.

The pressure so produced presses the platesf and q firmly upon therubber 0, whereby an impervious joint is produced between f and 11. Suchis the position and arrangement of the instrument while the sink is inuse. Vhile the cap is so adjusted, water which may be put into the sinkwill pass between the teeth 1' and find its way without additionalobstruction to and through the strainer which ordinarily guards themouth of the sink-pipe,in the usual manner. The teeth 1' operate as anadditional strainer, and prevent large crumbs and other matter frompassing under the cap and from too speedily clogging the mouth-strainerjust mentioned. The disinfectingsolution from the dish 0 is constantlyrunning or dropping at the predetermined rate from the lower end of thedischarge-pipe and nozzle m directly over and into the mouth of thesinlvpipe, whereby a continuous process of disinfection is establishedin and near the mouth of such pipe. Vhencver the sink is to remain indisuse for a day, a night, or any other considerable period, the stand 1should be removed from under the dish 0, and the latter should beclamped down with its lower surface or cushion, 0, immediately upon thebottom of the sink, so that an impervious joint may be made between thedish a and the upper surface of the bottom of the sink. The rubber ringor packing 0 is thus to extend over the extreme outer edge of thesink-mouth to which the same is thus applied. The removal of the stand(1 and the clamping down of the dish 0 in the manner last mentioned iseasily effected by means of the set-screwy, and affords a convenient andsufficiently frequent opportunity to removcl'rom the strainer whichguards the mouth of the pipe all accumulated small crumbs and otherobstructions. The dish 0, when so adjusted, operates as before, with thedifference that the same now operates as acap and shuts oiif allintercommunication between the inclosed atmosphere within the dish 0 andthe sink-pipe mentioned and the uninclosed atmosphere of the apartmentin which the sink is located. The continuous disinfection goes on asbefore. The above-described form of the dish 0 allows a constantexposure of the upper surface of the disinfectant-solution within thedish to the atmosphere occupying the otherwise vacant portion of suchcap, and the open funnel g 9 allows all vapors and disinfectinggaseswhich may be given off within the dish 0 to pass i'rcely into and aboutthe mouth of the sink-pipe. In this instrument it is obvious that anysort of disinfectant may be used which can by solutionbe brought to aliquid form. The annular packing or washer 0 may be omitted from theconstruction of this cap, or its place may be supplied by any otherdevice for creating an impervious joint between f and q, or between fand the sink-bottom, as the case may be, without departure from thespirit of my invention.

That I claim as my invention, and desire to secure by Letters Patent, is

1. The dish 0, provided with nozzles 76 and m, finger-piece h, stopperZ, and stop-cock a, substantially as shown, and operating as set forth,for the purpose specified.

2. The dish 0, provided with nozzles 7c and m, finger-piece h, stopperZ, and stopcock n, in combination with the set-screwj and arm .9,substantially as shown, and operating as described, for the purposespecified.

3. The dish 0 and standard q, in combination with the set-screw j andarm 8, substantially as shown, and operating as described, for thepurpose specified.

4. The dish 0, provided with the washer 0, in combination with thestandard (1, set-screw j, and arm 8, substantially as shown, andoperating as described, for the purpose specified.

In witness whereof I have hereunto set my name in the presence of twosubscribing wit nesses.
